GeForce 9600 GT 1GB vs Radeon HD 4850 1GB

Intro

The GeForce 9600 GT 1GB features a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and makes use of a 65/55 nm design. It features 64 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare those specs to the Radeon HD 4850 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR4 memory works at a speed of 993 MHz on this specific model. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
